Electric fields used in this way have long been used in commercial products, e.g. Amaxa nucleofection (https://bioscience.lonza.com/lonza_bs/CH/en/nucleofector-technology https://bioscience.lonza.com/lonza_bs/CH/en/nucleofector-tec...) and Neon electroporation (https://www.thermofisher.com/us/en/home/references/gibco-cell-culture-basics/transfection-basics/transfection-methods/electroporation.html https://www.thermofisher.com/us/en/home/references/gibco-cel...). I used both a decade back on mammalian cells. Bog standard electroporation has been used far longer back for bacterial cells.
